Taking and analyzing images of materials' microstructures is essential for quality control, choice and design of products. Today, the standard method in 'materialography' is to prepare 2d sections of materials, take 2d images of these sections using classical microscopy, and finally analyze the 2d images. However, the preparation of the 2d sections is difficult and bears the danger of destroying features of the microstructure. Moreover, interpretation of the 2d data in terms of geometric features of the 3d structure demands additional effort and is not always possible. Some tasks, e.g. measuring the size distribution of pores or analyzing the microscopic texture, are only possible using 3d image data. Insight into the 3d geometry of the microstructure of materials and measuring its characteristics are also prerequisites for using simulation techniques in order to choose and design materials according to desired product properties. Thus, taking and analyzing 3d images is not only desirable but necessary for a useful analysis of various microstructures. Microtomography (µCT) yields high resolution 3d images of the internal object's microstructure. µCT is on its way to become a standard method for taking 3d images as classical light microscopy is for 2d images. Hence there is a growing demand for processing 3d image data. There are several sophisticated tools for visualization of 3d images available. Usually, some processing is included as well. This is contrasted by a lack of possibilities to measure geometric characteristics. With respect to analysis, solutions tailored to special medical applications dominate. This book describes how to develop and apply efficient and versatile tools for geometric analysis. This books fits extremely well into our materials science programme. Also in the past we had several successful publications dealing with the topic of materials characterization, since the task of characterization is essential to every materials scientists, independent on what specific material he is interested in. The topic of 3D images is getting more and more imposrtant in this area, as shows the increasing amount of such images published in original research papers. Keywords for this book are: microstructures, materials characterization, X-ray tomography, confocal laser scanning microscopy, image analysis, image processing, modelling microstructures, open and closed foams
